By these words, which are part of Johathan's Swift's "A Modest Proposal" (1729), the author is referring to the claim to the throne of England, Ireland and Scotland by James Francis Edward Stuart, son of King James II. The latter was a Catholic King, who had already fathered a daughter named Mary; until James Francis Edward's birth, Mary, who had been raised as a Protestant, was the legitimate heiress to the English throne. James Francis Edward was a Catholic. The English Protestants were reluctant to have a Catholic king, as they did not wish to be under the political influence of the Pope. Therefore, they rebelled against James II, whom they overthrew. Mary and her husband William of Orange then became Protestant Queen and King of England, Ireland and Scotland. Ireland is the "home" to which Swift refers in this statement. Since the Irish were and are Catholic, they wished to help James Francis Edward Stuart regain his position as heir to the British, Irish and Scottish crown. Swift contrasts these irish men with those Protestants who would rather leave England than pay taxes to a Catholic king.
James Francis Edward's attempts to regain the crown were unsuccessful.
